[quote=383man]There is no special cap for the recovery system.
I disagree,they will all push coolant out,but they all won't suck it back,unless there is another style cap out there that I'm not aware of.

Actually you could be right. I will say all the caps I have used have the pressure and vacuum release and years ago in auto shop they never said the old caps did not have the vacuum release also. But maybe the caps I have used have been sine they went to the recovery system which was in the 70's I believe. And you are right that the old system did not need the vacuum release since they had no recovery tank to pull the coolant back in. I have never ben told they were different so I assumed they were not but I could be wrong on that and if I am I appoligize. Ron
